Hi all! I've been trying to upgrade our C++ backend to use the Node.js LTS 14.15.5. Previously, I would store and retrieve a Buffer object with a simple byte buffer as follows:
*Storing the data:* v8::Isolate* isolate = v8::Isolate::GetCurrent(); v8::Local<v8::Context> context = v8::Context::New(isolate); v8::Local<v8::Object> matObj = v8::Object::New(isolate); v8::Local<v8::Object> buffer = node::Buffer::Copy(isolate, reinterpret_cast<const char*>(source.data), source.total()).ToLocalChecked(); matObj->Set(context, v8::String::NewFromUtf8Literal(isolate, "data"), buffer).Check(); *Retrieving the data:* v8::Isolate* isolate = v8::Isolate::GetCurrent(); v8::Local<v8::Context> context = v8::Context::New(isolate); v8::Local<v8::Object> inputObj = input->ToObject(context).ToLocalChecked(); v8::Local<v8::Value> dataValue = inputObj->Get(context, v8::String::NewFromUtf8Literal(isolate, "data")).ToLocalChecked(); char* data = node::Buffer::Data(dataValue); Unfortunately, this now results in an assertion trying to check that dataValue is an ArrayBufferView: node[451684]: ../src/node_buffer.cc:243:char* node::Buffer::Data(v8::Local<v8::Value>): Assertion `val->IsArrayBufferView()' failed. 1: 0xa25510 node::Abort() [node] 2: 0xa2558e [node] 3: 0x9fd3fa node::Buffer::Data(v8::Local<v8::Value>) [node] 4: 0x7fa42d0320ae [/home/wlucas/CLionProjects/test.node] 5: 0xc066ab [node] 6: 0xc07c56 [node] 7: 0xc082d6 v8::internal::Builtin_HandleApiCall(int, unsigned long*, v8::internal::Isolate*) [node] 8: 0x14269f9 [node] Aborted (core dumped) Is there some type of casting required now, or should I be using the BackingStore with Uint8Array now instead of Buffer? Thanks for any advice!
